Withdrawal Strategies

Definition

A withdrawal strategy defines how much you pull from your portfolio each year in retirement and how you adjust for market performance, inflation, and longevity. The best-known is the "4% rule" — withdraw 4% in year 1 and adjust for inflation annually.

Why it matters in retirement

How much you can spend is the single most consequential number in a retirement plan. Bill Bengen's 4% rule, Guyton-Klinger guardrails, bucket strategy, and dynamic withdrawal all try to solve the same problem: maximize spending without running out of money.

Pros

  • 4% rule is simple and well-researched
  • Guardrails increase sustainable withdrawal rates
  • Bucket strategy reduces sequence risk psychologically

Cons

  • 4% rule ignores current valuations and yields
  • Fixed-rule approaches leave money on the table
  • None handle unexpected expenses gracefully

Common mistakes

  • Taking 4% rigidly regardless of market performance
  • Ignoring Social Security when planning withdrawal rate
  • Forgetting taxes — 4% gross is less after federal/state tax
  • Not rebalancing — letting equity drift below target increases failure rate
